JAMES F; DUFFY, OF PARK BIDGEIILLINOIS.

TOOL.

Application filed October 31, 1921. Serial No. 511,958.

To all whomt't may concern:

Be it known that I, JAMns DUFFY, a citizen of the United statea'residing'at' Park Ridge, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tools, of which the following is a description.

My invention relates to improvements in tools and particularly those intended to be used for testing or sampling cheese, butter, or the like, but the same may be modified in detail so as to be suitable for otheruses,

Among the objects of my invention is the production of a device of the kind described which is simple, convenient, durable,eco nomical, reliable, eflicient and satisfactory for use wherever ioundapplicable.

Another object of my invention to provide a testing tool or trier of the kind described which will be constructed of a single pieceot' sheet metal bent to-the desired shape. i i,

M any other objects and advantages of the construction herein shown and described will be obvious to those "skilled in the art from the disclosure herein given.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a plan view of the stamped-out blank showing the initial step in forming the tool; 1 a

Fig. 2 is a plan View showing the second step;

Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 2;

Fig. t shows the article as completed;

Fig. 5 isa sectional view taken substantially on the line 55 of Figure 4;

Fig. 6 is a sectional view taken substantially on the line 6-6 of Figure 4;

Figure 7 is a fragmentary longitudinal sectional view showing a modified'iorm of shank; and

Figure 8 is a sectional view taken substantially on the line 88 of Figure 7.

In the drawings, wherein I have illustrated the preferred embodiments of my invention, there is shown a blank of sheet metal of the desired material and size, preferably T shaped, the upright leg of said T forming the shank portion 1 oi? the tool and the head portion oi the T being preterablysubstantially square, as shown, and forming the handle portion 2 of the tool. The edges at the juncture of the head and vwhich may be examined or inspected.

shank port-ions are preferably cut in or rounded, as shown at 3, (Figure 1).

After th blankhasbeen cut to the shape shown in Figure 1 it is then placed in any suitable stamping machine or press and formed by dies or the like to the shape shown in F igures 2 and 3, wherein the shank portion is formed into a trough shape. The head portion of the T is also formed into a trough but with the portion toward the free end at extending substantially in a plane tangentially to thecurved portion of the handle (see Figure The curved portion of the handle is shaped into substantially semi-circular cross-section, while the remaining portion comprising the free end t is straight and lies in a plane ext-ending tangentially ot the semi-circular portion. i The next stepot tormingthe tool comprises forming or bending the straight or extending end 4 of the handle into a portion curved in cross section, by any suitable tools and process, as by stamping dies, rolling or the like, so that it meets the edge 5 of the handle parallel therewithto form a hollow cylindrical handle with a longitudinalseam therein where the meeting edges 1 and 5 come together. soldered, brazed, welded or otherwise secured at the seam if so desired. Thus there is formed a tool comprising a hollow cylindrical transverse handle and with a trough The same being shaped shank portion centrally of the ends of the handle and extending laterally or transversely thereof, the peripheral surface of the handle being a continuation of or tangential to the bottom surface of the shank.

In operation, the. shank portion of the tool is inserted in a cheese ora tub of butter, or the like, given a turn and then withdrawn, removlng a plug of thematerial If desired, the edges of the trough shaped shank may be sharpened at the side edges 6 and at the point or front edge 7 if so desired as most clearly shown in Figures 7 and 8, where 1 indicates the shank portion of the tool.

It will be noted that there is formed a tool of a single sheet of metal with a handle and shank portion, affording a strong, substantial and convenient article. The par ticular style of the handle affords a bearing for the handto push the same into the material and leverage to turn the same. The

by Letters Patent is:

device is sanitary, as well as attractive in appearance. The shank may be formed in the best shape to secure the sample to be taken, this depending to some extent on theparticular material.

Having thus described my invention it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, arrangement, construction and combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure lfA trier for food products made of a single sheet of material formed into an open trough-shaped shank portion whose channel variesin size progressively from end to end, and a handle portion arranged transversely of the shank and having a single seam therein lying in the same plane with the side edges of said shank. v

2. A blank for a trier for food products comprising a single. sheet of material having a shank portion that varies in width progressively from end to end and is adapted to be formed into an open trough, and a handle portion arranged transversely of the shank and having the corners formed by the meeting edges of the shank and handle portions rounded and cutback.

3. A. trier foriit'ood products made of a single sheet of material formed into an open arcuate trough-shaped shank portion whose channel varies in size progressively from end to end,a handle portion arranged transversely of the shank and having a single seam therein lying in the same plane with the side edges of said shank, and an areuate tab projecting from one edge of said handle portion and fitting into said arcuate trough to prevent passage of material between the shank and handle.

4. A trier for food products made of a single sheet of material formed into an open arcuate trough-shaped shank portion whose channel varies in size progressively from one end tothe other, a handle portion ranged transversely of the shank and having a single seam therein lying in the same plane with the side edges of the shank, and an arcuate tab projecting from edge of said handle portion and fitting into said arcuate trough to prevent the passage of material between the shank and the handle, the bottom surface of the shank being tangential to the exterior peripheral surface of the handle.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

JAMES F. DUFFY.
